ROLL HOLDER.

Application filed January 2, 1926. Serial No. 78,907.

This invention relates to a roll holder, and the primary object of our invention is to provide a holder for rolls, spools, reels or other devices on which stripmaterial is wound and adapted to be unwound, the holder accommodating two or more rolls, one of which is maintained in an active position and another in an inactive or reserve position so that it may replace an exhausted roll. It is in this connection that our device aims to save time by always having a roll ready for instant use and consequently oper ations rec uirin material from rolls can be performed without any material interruptions.

A further object of our invention is to provide a simple, durable and inexpensive roll holder wherein the shifting of an inactive roll to an active position discharges an exhausted roll, and the holder is corr structed so that neither of the rolls can become accidentally displaced, particularly when rolled material is being removed from the rolls.

The above are a few of the obects attained by the construction to be hereinafter de scribed, and reference will now be had to the drawing, wherein Fig. 1 is a side elevation of th holder;

lg. 2 is a plan of the same.

Fig. 3 is a cross sectional view of the roll holder; and

Fig. l is a side elevation of the roll holder showing the manner in which an exhausted. roll is discharged to be replaced by a full roll.

In the drawing, the reference numerals 1 and 2 denote side frames having lugs 3 connected by transverse feet or members l: that are angular in cross section and one or more of these members may be apertured, as at 5, so that the frame may be suitably anchored. relative to a support. litobvious that the frames 1 and 2 and the members t may be cast as a unitary structure or may be fabricated from senor rate parts.

The frames 1 and 2 have the confronting walls thereof provided with bosses 6 for transverse rods 7 and adjustable on said rods and adapted to be fixed thereto are sleeve portions 8 of roll centering guides 9, said guides being disposed in parallelism longitudinally of the frame and adapted to l'Oll engage the ends or heads of rolls 10 and 11 or the like placed on the frames. These guides may be adjusted for rolls of various widths and said guides will prevent transverse shifting of the rolls and consequently maintain the ends or heads of the rolls out of engagement with the holder frames 1 and 2. v

The rolls 10 and 11 are identical in construction with each roll having a spindle 12, pintles or the like and each roll is adapted for holding wound material 13, for instance thin sheet metal which may be unwound from the rolls into strip formation.

The upper edges 01 the frames 1 and 2 have inclined ways 1 L inclined downwardly from the rear end of the roll holder to the forward end thereof where the inclined ways terminate at hook shaped members serving as abutments for the spindles 1 of the rolls. The hook shaped members 15 arrest the descent of a roll spindle on the inclined ways 14 and a roll is adapted to be held by the members 15 until the material 13 is fully unwound and the roll exhausted, at which time the spindle of the roll is adapted to be raised to descend inclined ends 16 of the members 15 and be discharged from the holder. The outer sides of the holder frames 1 and 2, intermediate the ends thcreot', are provided with bearings 17 for fulcrum discharge arms 18 which have forward angular ends 19 adapted to engage a roll spindle or pintles and retain the roll spindle at the hookshaped member 15. The rear short ends of the arms 18 are normally engaged by the hook shaped ends 20 of release arms or cranks 21 carried by a rock shaft 22, iournalled in the rear upper ends of the holder fr: mes 1 and One end of the rock shaft 22 supports a hand lever 23 by which the shaft 22 may be rocked to lower the release arms 21 and actuate the discharge arms 18.

As shown in Fig. 1, the hook shaped ends 20 of the release arms 21 are adapted to hold the spindle 12 of the roll 10 so that this roll cannot descend to an active position in the holder While the roll 11 is in use. As this roll becomes exhausted the roll 10 is released by the arms 21 being lowered to free the spindle 12 of the roll 10. The release arms 21 bear on the rear ent that under short ends of the discharge arms 18 and tilt said arms, so that the empty roll 11.

is raised and discharged from the holder. As this is accomplished the discharge arms 18 control the'descent of the roll to an active position, because the spindle 12 of the roll 10 engages the upper edges. ofthe signed for pickling, cleaning, developing,

coating or other baths where rolls of sheet metal-or other material are immersed and adapted tobe unwound and emerge from the 'bath as treated thereby. In the metal industry, these baths are ordinarily of acid or a. solution injurious to the hands, there fore the roll holder has been designed as av r ck on to which loaded or full rolls may be dropped and held in activeand inactive positions; The shifting of the rolls is complished by an attendant of the pickling or cleaning apparatus by manipulating the lever 23 extending to a suitable height above the pickling or cleaning bath. Such useof theeroll -h older will be more fully understood by reference to .my companion applications'filed under even, date, and the purpose of this application is to claim the construction of the roll holder for general use. One embodiment of our invention has been illustrated, but it is to be understood that the structural elements aresusceptible to such variations and modifications as fall within the scope of the appended claims.

lVhat we claim is I 1. A- roll holder adapted for supporting active and inactive rolls, discharge arms adapted to displace an active roll when empty, and release arms adapted to hold a full inactive roll in, a reserve position and release said roll to replace the discharge active roll, said dischargcarmsbc- -1ng operatable by said release arms and corn trolling the movement of the inactive roll to an active position.

2. A roll holder comprising frames havng inclined ways adapted for supporting he spindles of active and inactive r .aid frames having hook shaped ends *etaining an active roll, roll discharging means supported by said frames adapted 'haped ends oi said irames, a roll releasng means carried by said frames adapted for supporting an inactive roll in a'reserve position and adapted to simultaneously release said inactive roll and causethe actuation of the roll discharging means, said roll discharging means controlling the move ment of the inactive roll,'so that the inactive roll. cannot *rou'd the active roll.

3. A roll holder comprising frames having inclined ways adapted'to support the spindles of rolls, one of which is retained or discharging an active roll from the hook in a reserve position at the rear ends of said frames and adapted to replace the other roll at the forward ends of said frames, roll centering means supported by said frames, roll discharge arms carried by said frames and adapted to raise and release the roll at the forward ends of said frames, and roll release, arms carried by said frames and adapted to simultaneously release the roll at the rear end of said frame and actuate said roll discharge arms.

4-. A roll holder as called for in claim 3, wherein the arrangement of the discharge and release arms is such that a released roll is prevented from crowding a discharge roll by contact with said rolldischarge arm.

5. A roll holder as called'i or in claim 3, wherein said roll centering m ans includes parallel adjustable guides between said frames. I

In testimony whereof We afiix our signatures.
